Through the administrator carries on the effective network administrative system to collect and analyze the data of the network equipment that not only can receive the warning information of the network in time to solve the problem , but also we can get the parameters of the network of different time . then the administrator can predict the development trend of the network , adjust the disposition of the network structure and guarantee that the information network is run reliably , steadily 针对实际需要,管理员通过网络管理软件对网络设备中性能参数的定时收集、存储和分析,不但可以得到网络性能实时的报警信息,及时解决问题,而且通过对不同时期,不同时间网络信息以及网络设备参数的分析,管理者可以预测网络的发展趋势,并根据这些信息对网络设备的配置进行调整,确保整个信息网络可靠、稳定的运行。
According to the characteristic of dtv front - end system and its development in the future , the network management software is divided into two functional parts , one is the device server and the other is the user server . all the front - end equipments are managed by the device server , and the communication model between equipments and the device server is c / s structure base on tcp / ip protocol . the requests from users for browsing or modifying device parameters are managed by the user server , and the communication model between users and the user server is b / s structure based on tcp / ip protocol 根据数字电视前端系统的特点及未来发展的需要,本论文总体上把整个网管平台软件分为了设备服务器和用户服务器两个功能模块,所有的前端设备由设备服务器统一管理,它们之间的通信是基于tcp / ip协议的c / s结构;用户服务器负责处理用户浏览或修改设备参数的请求,它们之间的通信是基于tcp / ip协议的b / s结构。
The unit and whether the connection between devices is right or not can be judged easily . the functions talked above are not enough to software , the common used edit method and the setup of power plant graphics are also required , they can be realized by inheriting and refer to the method in the units of delphi6 . 0 . as the interface of user and system , except the function of graphic creation it still requires to convert the original data to make it meet the demand of fault analysis 同时该模块作为用户与本系统的计算机接口，除了完成系统图的建立之外，还必须对设备电气参数进行归算，使之满足故障分析与保护整定的要求；要能提供进入故障分析与保护整定模块的接口，完成系统地连接功能；最后为了能正确处理设备的有关参数，本文还介绍了在进行故障分析时将设备参数进行转化的工程处理办法，具有很强的实际意义。
The paper involved follow contents : a . introduced the basic theory of some basis theories about the layout to materials handling systems ; b . developed a cad software , in the development , the follow technical problem : 1 ) found the self - contained graphic and parameter aggregate of the equipment according to the work system of ksec ; 2 ) realized the parametric designing and changing of the mhs equipment by developing autocad using the vba as the tool ; c 论文主要包括以下内容： 1 、对物流系统规划的有关理论作了介绍； 2 、开发了计算机辅助设计软件，在软件开发中主要解决了以下技术问题： a )根据昆船物流公司的工程标准建立了完备的设备图形库及设备参数数据库， b )通过vba对autocad进行二次开发，实现了各种设备的参数化设计并可以完成自动修改。
The work of relaying calculation of power plant mostly is done by the staff of relaying squad , so a great deal of calculation is done in the relaying workroom . but the query and browse of the setting books , the parameters of equipments and the calculation books can be done in many departments in power plant , even in the power management department 电厂的继电保护整定工作主要由保护班工作人员完成，因此大量的计算集中在保护班工作室；而电厂设备参数的浏览、定值单、整定书的浏览查询以及对发电厂故障情况分析结果的浏览却分布在电厂的各个部门，甚至从长远考虑可能分布到其它电力管理部门。
